With the development of the research on ChineseBuddhismliterature,it is necessary to establish the subject by which Chinese Buddhism literature is dealt with,namely Chinese Buddhism philology . The Chinese Buddhism philology,taking the Chinese Buddhism literature and the work of Buddhism literature as the object,studies the history and rules about Buddhism literature and provides the theories for the work of Chinese Buddhism literature . The Chinese Buddhism philology is different from the study on Chinese Buddhism historical data,the reorganization and the research on the Chinese Buddhism literature . On the other hand,it has many relations with the latter two . There are three reasons to establish the Chinese Buddhism philology :First,the western methods of Buddhism philology are not suitable for the Chinese Buddhismliterature .Second,therearemany differences between theChineseBuddhismphilology and the common philology . Finally,the Chinese Buddhism literature is important in the entire history of the Chinese philology.
